Microsoft is looking at starting a pilot project of its ‘White-Fi’ technology that uses the unused spectrum in frequencies used for broadcasting of television signals, and is likely to offer solution to tackle the problem of last mile broadband connectivity in the country. “In a country of massive change, digital divide can pose serious challenge. In all the initiatives by the government — Digital India, Swachh Bharat or Jan-Dhan Yojna — technology has a role to play, and we want to be part of it,” Microsoft India Chairman Bhaskar Pramanik said, adding that at present, the company was talking to all stakeholders, including the government, for its ‘White-Fi’ technology to provide last mile connectivity. What is White Fi/Space? White Space refers to the unused broadcasting frequencies in the wireless spectrum. Television networks leave gaps between channels for buffering purposes, and this space in the wireless spectrum is similar to what is used for 4G and so it can be used ...

While drones were mostly used by the military and navy, they have now become very popular among civilians and also as a means of delivering packages. Each company comes with something new and more high-tech than the others and the competition is at a very high level. What is Google's Project SkyBender? The technology company is currently developing the program, codenamed Project SkyBender, to utilize solar-powered drones equipped with millimeter-wave radio transmitters that could send out next-generation 5G wireless Internet signals. So why drones?  Why not bounce such signals off of cell towers? It has to do with the way 5G works, by way of millimeter wave radio transmissions. Theoretically, millimeter wave frequencies (30 to 300 gigahertz) can transmit data up to 40 times faster than current 4G LTE wireless tech — but the shorter breaks in 5G waves, while allowing for an increase of data carry do shorten the range of transmission, can be scattered by natural at...

What Is 5G, Exactly? 5G is a term used to describe the forthcoming fifth generation of mobile network technology. Right now, it doesn't signify any particular type of technology. While 4G has become synonymous with LTE, there's been no publicly agreed upon standard for 5G networks. However, a couple of likely technologies are emerging. 5G networks will use a type of encoding called OFDM ( Orthogonal Frequency Division Multiplexing ) , which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though. The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks: Data rates of tens of megabits per second for tens of thousands of users 1 Gb per second simultaneously to many workers on the same office floor Several hundreds of thousands of simultaneous connections for massive wireless sensor  network Spectral efficiency signifi...

What is HaLow? There's a new wireless networking protocol in town and it comes to bring connectivity to the Internet of Things. Wi-Fi HaLow (pronounced "HAY-low") is a marketing name used for products that utilize the IEEE   802.11ah   wireless technology, which offers longer range and lower power connectivity than traditional WiFi -certified products. Wi-Fi HaLow is the latest specification from the Wi-Fi Alliance looking to expand the range of Wi-Fi's connectivity options.  Wi-Fi HaLow will be able to easily work through walls and large barriers because of the propagation capabilities of low-frequency radio waves, as it will operate in the unlicensed wireless spectrum below 1GHz. HaLow’s range will be nearly double the range of today's Wi-Fi, with estimates extending as high as a whopping 3,280 feet.   HaLow is designed for the Internet of Things , designed to connect multiple devices wirelessly, over extended distances and using lower power...

What is Li-Fi? Light Fidelity or  Li-Fi   is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. Li-Fi uses common household LED (light emitting diodes) lightbulbs to enable data transfer, boasting speeds of up to 224 gigabits per second . The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. Haas envisioned light bulbs that could act as wireless routers. How it works? Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves while Li-Fi runs on visible light . As we now know, Li-Fi is a Visible Light Communications (VLC) system. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into 'stream-able' content. Visible Spectrum An LED lightbulb is a semi-conductor light source meaning that the constant current of...
